Pew applies a rigorous, analytical approach to improve public policy, inform the public, and invigorate civic life. Overview Taken together, the seven most commercially important tuna species are among the most economically valuable fishes on the planet. Collectively, skipjack, albacore, bigeye, yellowfin, Atlantic bluefin, Pacific bluefin, and southern bluefin tuna1 inhabit all of the tropical and temperate waters of the Earth’s oceans—and support artisanal and industrial fishing wherever they exist. Canned and other shelf-stable tuna products provide plentiful and inexpensive protein to markets around the world, while smaller amounts of high-quality tuna steaks and sashimi make their way to affluent markets in Asia, Europe, and North America. Ecologically, tuna are a vital part of marine systems. Their importance in food webs as predators and prey is difficult to monetize; however, these iconic species are known to play a fundamental role in open ocean ecosystems.2 That makes maintaining their health critically important to human communities that rely on them for food and economic well-being, particularly at a time of global ocean change. This report, in which The Pew Charitable Trusts presents the first effort to estimate the full global value of the primary commercial fisheries targeting these seven tuna species and the value of the resulting products, summarizes and discusses the findings of a much more detailed analysis that Pew commissioned from Poseidon Aquatic Resource Management Ltd., an independent fisheries and aquaculture consultancy based in the United Kingdom.3 Estimating the economic contribution of these fisheries informs and highlights the urgency of ensuring that the systems that govern the global ocean are robust and effective. Action is needed to guarantee a healthy and stable future for these species, as well as for the communities and businesses that depend on them. The findings are based on information gathered on tuna fisheries and markets for 2012 and 2014.4 Based on the analysis of available data, commercial fishing vessels in 2012 landed about 4.6 million metric tons of tuna worldwide. The estimated dock value, or amount paid to fishermen, was US$12.2 billion.* The estimated end value of this tuna—the total amount paid by the final consumer—was at least $33.3 billion. The estimate rose significantly when the entire price of a can of tuna, beyond the value of the fish alone, was used. In that case, the end value in 2012 was estimated to be $41.6 billion.5 In 2014, the volume of landed tuna rose to 4.99 million metric tons with an estimated dock value of $9.8 billion. The estimated end value remained similar to that in 2012 due to falling fish prices, and was $32.9 billion, or $42.2 billion when including the full canned product price.

A total value of tuna, incorporating sport fishing and in-the-water ecosystem benefits of living tunas, among other things, would be much higher. Therefore, these numbers should be considered conservative. The methodology used to calculate these global estimates allows for values to be broken down by region, species, and fishing gear. For example, the Pacific Ocean is home to the world’s largest tuna fishing grounds, making this region the largest contributor to total global sales values. According to the analysis, the end value of Pacific tuna when including the full canned tuna product price surpassed $22.7 billion in 2014. When looking at individual species, skipjack tuna—most often found in cans—generates the highest estimated amount of revenue because of the volume caught each year. When analyzing individual fish, the three bluefin species—Pacific, southern, and Atlantic—are by far the most highly prized; a single bluefin typically fetches more than a ton of skipjack. Several populations of the most commercially important tunas, particularly the bluefin species, have been fished to levels that scientists and managers consider too low.6 The values reported here help make a convincing economic case for improving the management of the world’s tuna fisheries. Stocks of Pacific bluefin, southern bluefin, and Atlantic bluefin, Atlantic and Pacific bigeye, and Indian Ocean yellowfin are all currently overfished. 7 That means they have been fished down to a population size that no longer supports the maximum level of sustainable fishing and threatens their role in marine ecosystems. As a result, these stocks deliver less overall value to global tuna fisheries than they could if they were managed differently. As with all fisheries, maximizing the value of a species requires management that recognizes the productivity of healthy populations and minimizes the risk that the fishery will end up in an overfished state. Given the increasing number of tuna fisheries classified as overfished, improved management of these populations would likely, in time, improve catch rates and financial returns. The reality is that fisheries management decisions continue to be based predominantly on the short-term economic bottom line—the amount of value gained or lost by fishing on any given day. That must change. Fishery managers should enact policies that at a minimum restore depleted stocks to healthy levels, which should include setting science-based catch limits and developing systems of pre-agreed management actions that would be triggered when stocks fall below certain levels. With a conservative annual value over $40 billion, tuna fisheries represent a significant component of the global economy. Improved management of these fisheries and conservation of tuna stocks are critical to sustaining the health and well-being of marine ecosystems, as well as the industries and coastal peoples who rely on the life in these waters for income and food. 2 Adam Baske Richard Herrmann Tuna ecology and history The tunas are some of the world’s fastest fishes, with sleek bodies designed to achieve maximum speeds. The species referred to in this report migrate thousands of miles over their lifetimes, among oceans, national waters, and fisheries management regimes. Despite some similarities, such as the ability of most tunas to regulate their body temperatures (unlike most other fishes), there are significant biological differences among these species. Tuna can range in size from just a few kilograms up to 680 kg (nearly 1,500 pounds), or roughly the size of a full-grown polar bear. Some tuna species live only a few years, while others can survive for decades. All tunas are open ocean predators that eat fish, squid, and crustaceans. While they occupy a top position in the food web, juvenile tunas are also important to larger predators such as sharks, whales, and even other tunas. Coastal communities around the world have relied on tuna for centuries, and the influence of these species can be found in music, art, and literature.

  • Do Some Atlantic Bluefin Tuna Skip Spawning?
    SCRS/2006/088 Col. Vol. Sci. Pap. ICCAT, 60(4): 1141-1153 (2007) DO SOME ATLANTIC BLUEFIN TUNA SKIP SPAWNING? David H. Secor1 SUMMARY During the spawning season for Atlantic bluefin tuna, some adults occur outside known spawning centers, suggesting either unknown spawning regions, or fundamental errors in our current understanding of bluefin tuna reproductive schedules. Based upon recent scientific perspectives, skipped spawning (delayed maturation and non-annual spawning) is possibly prevalent in moderately long-lived marine species like bluefin tuna. In principle, skipped spawning represents a trade-off between current and future reproduction. By foregoing reproduction, an individual can incur survival and growth benefits that accrue in deferred reproduction. Across a range of species, skipped reproduction was positively correlated with longevity, but for non-sturgeon species, adults spawned at intervals at least once every two years. A range of types of skipped spawning (constant, younger, older, event skipping; and delays in first maturation) was modeled for the western Atlantic bluefin tuna population to test for their effects on the egg-production-per-recruit biological reference point (stipulated at 20% and 40%). With the exception of extreme delays in maturation, skipped spawning had relatively small effect in depressing fishing mortality (F) threshold values. This was particularly true in comparison to scenarios of a juvenile fishery (ages 4-7), which substantially depressed threshold F values. Indeed, recent F estimates for 1990-2002 western Atlantic bluefin tuna stock assessments were in excess of threshold F values when juvenile size classes were exploited. If western bluefin tuna are currently maturing at an older age than is currently assessed (i.e., 10 v.

  • NOAA's Description of the U.S Commercial Fisheries Including The
    6.0 DESCRIPTION OF THE PELAGIC LONGLINE FISHERY FOR ATLANTIC HMS The HMS FMP provides a thorough description of the U.S. fisheries for Atlantic HMS, including sectors of the pelagic longline fishery. Below is specific information regarding the catch of pelagic longline fishermen in the Gulf of Mexico and off the Southeast coast of the United States. For more detailed information on the fishery, please refer to the HMS FMP. 6.1 Pelagic Longline Gear The U.S. pelagic longline fishery for Atlantic HMS primarily targets swordfish, yellowfin tuna, or bigeye tuna in various areas and seasons. Secondary target species include dolphin, albacore tuna, pelagic sharks including mako, thresher, and porbeagle sharks, as well as several species of large coastal sharks. Although this gear can be modified (i.e., depth of set, hook type, etc.) to target either swordfish, tunas, or sharks, like other hook and line fisheries, it is a multispecies fishery. These fisheries are opportunistic, switching gear style and making subtle changes to the fishing configuration to target the best available economic opportunity of each individual trip. Longline gear sometimes attracts and hooks non-target finfish with no commercial value, as well as species that cannot be retained by commercial fishermen, such as billfish. Pelagic longline gear is composed of several parts. See Figure 6.1. Figure 6.1. Typical U.S. pelagic longline gear. Source: Arocha, 1997. When targeting swordfish, the lines generally are deployed at sunset and hauled in at sunrise to take advantage of the nocturnal near-surface feeding habits of swordfish. In general, longlines targeting tunas are set in the morning, deeper in the water column, and hauled in the evening.

    QUALITY STATUS REPORT 2010 Case Reports for the OSPAR List of threatened and/or declining species and habitats – Update Nomination and biomass of older fish since 1993. The reported catch for the East Atlantic and Atlantic bluefin tuna Mediterranean stocks in 2000 was 33,754 MT, Thunnus thynnus about 60% of the peak catch in 1996 although this is probably an under-estimate because of increasing uncertainty about catch statistics (ICCAT, 2002). The best current determination of the state of the stock is that the Spawning Stock Biomass is 86% of the 1970 level. This is similar to the results obtained in 1998 in terms of trends, but more optimistic in terms of current depletion. Nevertheless, the International Commission for the Conservation of Atlantic Tunas (ICCAT) Geographical extent considers that current catch levels are not OSPAR Regions: V sustainable in the long-term (ICCAT, 2002).

Block1 1Tuna Research and Conservation Center, Stanford University, Hopkins Marine Station, 120 Oceanview Boulevard, Pacific Grove, California 93950, USA 2Present address: Biology Department, Woods Hole Oceanographic Institution, Woods Hole, Massachusetts 02543, USA ABSTRACT: We analyzed the movements and diving behavior in relation to water column structure of 35 electronically tagged Atlantic bluefin tuna (176 to 240 cm in length at tagging) during their spring–fall period of occupancy of the Gulf of Maine, Canadian Shelf, and neighboring off-shelf waters from 1999 to 2005. Tagged fish arriving in this study region in March–April initially occupied weakly stratified off-shelf waters along the northern Gulf Stream. As waters over the continental shelf warmed in June, the fish shifted onto the shelf. Sea surface temperatures occupied were relatively constant in both off- and on-shelf waters (April–September monthly medians varying from 16.1 to 19.0°C). Dives made in the stratified waters of the shelf during summer and fall were significantly more frequent (up to 180 dives d–1) and fast (descent rates up to 4.1 m s–1) than in weakly stratified off-shelf waters occupied during spring, defining dives as excursions below tag-derived estimates of the surface isothermal layer depth (ILD). The duration and depth of dives also decreased significantly in associa- tion with changing water column structure, from medians in off-shelf waters during April of 0.45 h and 77.0 m, respectively, to 0.16 h and 24.9 m in August.
